As shown in Figure 1, gross imperfection detection machine of the invention includes detection platform 10 and image acquiring device 20.Wherein,
Detection platform 10 is set on pedestal 60, and detection platform 10 is configured as carrying display panel 30 to be detected；Image obtains dress
It sets 20 and is set to 10 top of detection platform, image acquiring device 20 is configured as vertically taking display panel 30 to be detected
Picture and inclination capture.Vertical capture and inclination capture are carried out to display panel 30 to be detected using image acquiring device 20, it can
Instead of Manual Visual Inspection, and vertical capture and inclination capture can comprehensively obtain the photo of display panel 30, so as to aobvious
Show that panel 30 is comprehensively detected, improves detection efficiency and detection success rate.
Specifically, image acquiring device 30 includes first camera 21 and second camera 22, and first camera 21 is configured as hanging down
Directly obtain the image of display panel 30 to be detected；Second camera 22 is configured as inclination and obtains display panel 30 to be detected
Image.It is taken pictures using two cameras, and the crevice projection angle of two cameras is different, to be avoided that wrong detection, that is, avoids
Erroneous detection.
In order to further avoid erroneous detection, as shown in Fig. 2, the tilt angle of the second camera 22 in the present invention is greater than evacuation angle
ɑ is spent, avoids angle ɑ are as follows: the optical path of second camera 22 enters view field and optical path of the shelter 40 on display panel 30 and prolongs
Long line 23 just without angle when blocking object 40, blocks the lower section that object 40 is located at display panel 30 to be detected.It is logical
Crossing makes the tilt angle of second camera 22 be greater than evacuation angle ɑ, in order to eliminate below display panel 30 to be detected
Influence of the supporting element (blocking object 40) to imaging.
In order to facilitate control second camera 22 tilt angle, the present invention in, second camera 22 be connected with instruction its inclination
The index dial of angle.The tilt angle of second camera can be intuitively adjusted using index dial.
Because there is evacuation angle, for cooperating the light source of image acquiring device 20, the present invention is detecting light source setting
The bottom of platform 10 provides illumination to display panel 30 to be detected from the lower section of display panel 30 to be detected.By light source
It is set as backlight, compared to setting at side (side light source), it can be ensured that uniform, the consistency of illumination, it is ensured that image acquiring device
Capture is accurate.
Image acquiring device 30 is set in transfer mould group 50 by the installation for image acquiring device 30, the present invention, is moved
It carries mould group 50 to be configured as that image acquiring device 30 is driven to translate along first direction and second direction, first direction and second direction
It is perpendicular.It is specific to be carried using two straight line mould groups, the transfer mould group is constituted, straight line mould group is existing structure, here no longer
It repeats.Using transfer mould group 50, image acquiring device 20 can be made to obtain the image of entire display panel 30 to be detected, realized complete
Substrate detection, further avoids missing inspection.
In addition, the spacing between detection platform 10 and image acquiring device 20 can be adjusted.By adjusting detection platform 10
With the spacing between image acquiring device 20 so that the position of image acquiring device 20 meets operating distance.It is specific to adjust knot
Structure is e.g. set on pedestal 60, elevating mechanism is Conventional mechanisms, and which is not described herein again in which will test 10 lift of platform.
For the ease of the display panel 30 with detection to be placed in detection platform 10, detection platform 10 of the invention can
Opposite pedestal 60 translates.Detection platform 10 is translated, is staggered with image acquiring device 20, so that the feeding of detection platform 10 is grasped
Make.
After display panel 30 is placed in detection platform 10, need that display panel 30 is made to be fixed on required position.Therefore,
The present invention is provided in detection platform 10 and leans on bit architecture 11 to what display panel 30 to be detected was positioned.By bit architecture 11
Principle is supported with the edge of display panel 30, and display panel 30 is pushed to be moved to required position.It is existing knot by bit architecture 11
Structure, details are not described herein again.Display panel 30 to be detected is positioned, in the case where accurate positioning, to be detected aobvious
Show that panel 30 carries out capture, it is ensured that verification and measurement ratio.
In order to make the gross imperfection detection machine be suitable for Manual Visual Inspection, the detection platform 10 in the present invention can be overturn.It turns over
Turn detection platform 10 to meet detection angles, manually to carry out visual inspection to display panel 30 to be detected at an appropriate angle.
To sum up, gross imperfection detection machine of the invention can replace artificial inspection, improve detection efficiency and detection success rate, together
When be also applied for manually examining.
The technical principle of the invention is described above in combination with a specific embodiment.These descriptions are intended merely to explain of the invention
Principle, and shall not be construed in any way as a limitation of the scope of protection of the invention.Based on the explanation herein, the technology of this field
Personnel can associate with other specific embodiments of the invention without creative labor, these modes are fallen within
Within protection scope of the present invention.
